Description: Node security refers to the protection of individual nodes within a network, ensuring they are safeguarded against cyberattacks and unauthorized access. Each node, which can be a server, computer, or IoT device, represents a critical point in the network infrastructure. Node security involves implementing security measures such as firewalls, antivirus, and intrusion detection systems, as well as enforcing robust access and authentication policies. Additionally, it focuses on vulnerability management and the constant updating of software to mitigate risks. The importance of node security lies in the fact that a single compromised node can serve as a gateway for broader attacks, affecting the integrity and availability of the entire network. Therefore, an effective security strategy must consider each node as an essential element requiring individualized attention and protection, thus contributing to the overall security of the network and its connected devices.
